What short-outage Gulf Power Co filings show

Gulf Power Co is an investor-owned utility operating in Florida under EIA identifier 7801. Customer count is not reported in the current EIA filing. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.

In 2021, the average Gulf Power Co customer experienced 74.4 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 0.78, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 40.4 minutes, the gap between that figure and the headline 74.4 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 2 years of continuous reporting (2020–2021) for Gulf Power Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 1934.9 to 74.4 minutes across that span, a direction regulators and prospective customers tend to watch closely. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Gulf Power Co's other reported years.
